Koeman was asked about Klopp running down the Estadio Alfredo di Stefano after their Champions League defeat to Real Madrid in midweek.
The Barca coach stated: "It is an attempt to discredit a big club like Real Madrid.
“Real have taken the opportunity to renovate the Santiago Bernabéu, now that there is no public presence. I am convinced that the field will be fine.
"It is not an important topic for me."
